Underground Storage of Carbon Dioxide Reduces Emissions

29.06.2004


A new approach that is one of the first to successfully store carbon dioxide underground may have huge implications for global warming and the oil industry, says a University of Alberta researcher. Dr. Ben Rostron is part of an extensive team working on the $28 million International Energy Agency Weyburn CO2 Monitoring and Storage Project—the largest of its kind—that has safely buried the greenhouse gas and reduced emissions from entering the atmosphere.



“It’s one thing to say that underground is a great place to store carbon dioxide, but it’s another thing to be able to prove it as we have done,” said Rostron, from the U of A’s Faculty of Science and a co-author on a paper appearing today in GSA Today, a journal published by the Geological Society of America. “We have been able to show that you can safely capture carbon dioxide that would otherwise go back into the atmosphere, and put it back into the ground. It’s very exciting work.”

Carbon dioxide is a naturally occurring greenhouse gas in the atmosphere whose concentrations have increased as a result of human activity, such as burning coal, oil, natural gas and organic matter. CO2 emissions have been linked to global warming, and there has been a worldwide effort to reduce those emissions and their effects on the planet. The efforts in this project are one way for Canada to meet targets under the Kyoto Protocol, for example.


Carbon dioxide sequestration is being evaluated internationally as a viable means of long-term carbon dioxide storage. Rostron is part of the project started in 2000 to investigate the technical and economic feasibility of storing the gas in a partially-depleted oil reservoir in Saskatchewan. The researchers are working with Encana Corporation on their 30-year commercial carbon dioxide enhanced oil recovery operation which is designed to recover an incremental 130 million barrels of oil from the Weyburn field in Saskatchewan . The gas comes from the United States, where it is compressed and sent through a pipeline to the Weyburn field. There, Encana injects it into the reservoir and the results are observed by the project scientists and stakeholders—including regulatory agencies and government officials. More than 1.9 billion cubic metres have been injected so far.

Not only has the project demonstrated one way for the industry to economically reduced carbon dioxide emissions that would have otherwise gone into the atmosphere, but it allows the oil industry to pump carbon dioxide into its wells and produce extra oil, said Rostron. The work also demonstrates that geological sequestration can be successful, enabling wider application in other parts of the country and the world, he said.

“The oil companies have seen incremental production close to what they predicted and from the scientists’ point-of-view, we’ve been able to see a response to our techniques and been able to monitor it very, very closely,” said Rostron, the hydrogeology co-ordinator on the project. “Everything we’ve done has shown us this is a good place to store carbon dioxide.

“Countries around the world are spending millions to investigate this same technique and we’ve been able to do with success.”

The project is co-ordinated by the Petroleum Technology Research Centre and is sponsored by Natural Resources Canada, the U.S. Department of Energy, Alberta Energy Research Institute, Saskatchewan Industry and Resources, the European Community, and 10 industrial sponsors. Research is being conducted by universities, industry, federal and provincial government agencies in North America and Europe.

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
